IEANS FOR SECURING IN PLACE AND RENDERIN'G USEFUL DEFLATED PNEUMATIC TIRES.

Specification of Letters Patent.

Application filed March 5, 1913. Serial No. 752,183.

ing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Means for Securing in Place and Rendering Useful Deflated Pneumatic Tires, of which the following is a specification, reference being had therein to t e accompanying drawing.

This invention relates to means for securing in place and rendering useful deflated pneumatic tires.

In the employment of what is now commonl known as the quick-detachable and clenc er tires used largely on motor cars, when the tire becomes deflated or collapsed, it is necessary. to remove the same from the wheel rim, inasmuch as the maintenance of the tire on the wheel rimis dependent upon the inflation of the inner tube. The air pressure maintains the lock, which latter becomes ineffective as such when the tire is deflated.

willbe'rendered efi'ective for maintaining the tire properly on the "rim. A further purpose, of the invention is that of rendering useful a deflated tire or shoe as a resilient different mechanical means employed, there is shown in the accompz inymg drawing, an

i't e tire broken away and the appliance or mom 1; or tire for the wheel. While the inventlon can be embodied in many different forms and a multitude of embodiment of a structure designed to serve well the pur ose for which the invention is intended. T e invention isnot limited, how- Over, to the particular construction shown and described,

'Eig'urel is an elevation of a. wheel caringlthe'pneumatic tire showing parts of device "applied to the tire, the latter being of a conventional quick detachable tire structure. with an annular split lock or key ring B and the clencher or securing ring C fash- 1oned to engage the hooked edge of the tire or shoe, the opposite edge of the rim A belng conveniently and usually shaped into hook formation. Of course, it is to be understood that any form of rim may be employed, but the one shown is that of a conventional type. D represents the shoe or tire having the hooked edges (13.

D represents a band conveniently in the form of a wire cable divided by preference into two sections. These sections have their ends looped as at d and are connected re spectively with tightening devices E and F. The tightening device E comprises conveniently a rigid frame member of substantially U-shaped cross section. This member is formed ,with two oppositely arranged elongated slots 6. E, E designate head blocks fashioned to fit the inner face of the frame E and having at opposite edges promoting studs 01' pins 0' fitting in the elongated slots 6. Intermediate of the head blocks is a tightening screw member E" having its opposite ends threaded in a reverse order respectively, the end portions fitting threaded openings in the head blocks. Centrally of the screw is a wrench hold 6 rigid with the screw so that the screw may be turned in either direction and simultaneously move the head blocks toward and from each other. Each head block is provided with a loop E with which. the looped end of the cable members are connected, as shown in Fig. 1.

The opposite ends of the cable sections are connected to a tightening device comprising conveniently an elongated tubular member F having slots f inits opposite sides the This 11m 1s, as usual, equipped pockets f, f". The ends of the cables are looped over transverse bars F the ends of which project through the slots 1n the tube.

These bars are designed to be drawn toward each other and seated in the pockets or depressions in the tube at the center thereof, thus drawing up and tightening the cables. A convenient device for drawin the bars toward the center of the tightening device or tube is illustrated in Fig. 8, the same comprising conveniently a frame or body member H having at one end a hook it fashioned to engage the end of the part F.- The hook is conveniently connected with the frame by a chain or other flexible means. The op 0- site ends of the frame H have a threa ed bore through which passes the screw H. This screw H has a crank'at one end, while its opposite end has connected thereto by a suitable chain or other means, hooks h, designed to engage the. opposite ends of the bar F. After the two cross bars F have been positioned in the; pockets or recesses at the center of the tube F, it may be found advisable or convenient to apply a means for securing them against accidental displacement. For this purpose, a. plate L may beemployed, the same being arranged to project over the securing bars and adjustably held in position by a bolt and nut Z passing through the upper portion of the tube F. D

In,the more general application of the invention, it is desirable to place on the cables rubber tubing of a diameter to materially add to the diameter of the device, as illustrated at K in the drawing, for purposes presently to be described.

In the useof the device, after the tire has been deflated, the compressing ring or cables are placed overthe same centrally, constituting in that particular an encompass ng ring or band. The drawing up, stretching and fastening device F is then employed to draw the ends of the cable toward each other, the operation being substantially that of applying the hook it to the bars F through the loops atone end, while attachin the opposite hook h to the end of the tube F. The bars through the loops are thus drawn into the pocket at the center of the tube. The device H is then reversed and the bar through the loop at the opposite end is likewise drawn toward thccenter, thus taking up the slack and tightening the band. It has been ascertained that approximately from twelve to fifteen inches of movement is required to completely compress the tread of the tire and by thp device illustrated and designed as the tightencr F, the major portion of this slack can be taken up readily. Thereafter for complete tightening, the turn buckle type, as designated by the reference E shown in Figs; 2 and 3 ma be operated so as to with exactness secure te proper ten- The rubber shoe or tire is thus 'held' firmly on the rim much the same as they are held in position by the compressed air of the inner tube when the tire is inflated. \Vhen the tire has been drawn down in the manner above described, the side portions will constitute cushion tires supporting in that particular largely the weight of the vehicle or its portion of the weight of the vehicle, preserving the rim of the wheel. The size of the cable or band with its rubber coating may be such and conveniently is, as to constitute in effect a supplemental tread at the center of the shoe. The device when properly applied will serve also to prevent,

skldding. a

While the tightening devices have been found to be effective, it is to,be understood that either one or the other may be omitted. Obviously, any other form or type of device which will tend to draw the ends of the hand up may be employed. The device may be easily collapsed and packed in the tool chest of the machine with but little trouble. Chains or ropes may be employed in lieu of a cable, the underlying principle of the invention being that of a device which can be employed for drawing downthe center of the tread of the deflated tire so asto maintain the tire in place on the rim and render the same useful for cushioning purposes and as a usable tire.

In the specification where the term tire is employed it. is to be understood that it applies to that portion of the tire as a whole which is generally termed the shoe,.it being understood the invention comprehcnds the ameter of the band being less than the width of the tire, and means for tightening the band to press the tread of the de d tire inwardly toward the rim and ntain'the tire in engagement with the first mentioned tire retaining means.

2. The combination pith a rim provided its weapon of the deflated tire, said device comprising a band adapted to extend eircumferentially of the tire and embrace the tread portion thereof, said band having a flexible covering and separate ends, and means for drawing the ends of the band together to tighten the band on the tire, substantially as described.

3. The combination with a rim and a defluted tire havin a, tread ortion, of non elastic detachab e means the tread portionin a circumferentially in wardlg disposed position, substantially as descri ed.
